True 4-in-1 Sensing: Tracks temperature, relative humidity, barometric pressure, and volatile organic compounds (VOC) gas levels simultaneously.

Indoor Air Quality (IAQ) Monitoring: Features an onboard metal oxide gas sensor that detects paints, lacquers, cleaning agents, smoke, and other VOCs to give you a clear picture of air safety.

High-Accuracy Altitudes: With its highly precise barometric pressure sensor, it can determine altitude changes down to a matter of centimeters, making it excellent for high-altitude projects and navigation.

Dual Interface Support: Supports both I2C and SPI communication protocols, making it fully compatible with Arduino, ESP32, Raspberry Pi, and STM32 microcontrollers.

Ultra-Low Power Consumption: Optimized for battery-powered and IoT applications, with customizable power modes to save energy.
